我有一个 EAR 文件 (JEE6),其中包含一个 ejb-jar (sample-ejb) 文件和一个 war 文件 (sample-web)。这是结构:
sample-ear
|----sample-ejb.jar
| |---TestEjb.java (@Singleton)
|
|----sample-web
|---StartupEjb.java (@Singleton,@Startup)
|---TestListener.java (@WebListener)
当我想将 TestEjb 注入 StartupEjb 或 TestListener 时:
@EJB
private TestEjb testEjb;
我收到以下错误:
玻璃鱼:
Caused by: com.sun.enterprise.container.common.spi.util.InjectionException: Exception attempting to inject Remote ejb-ref name=com.sample.StartupEjb/testEjb,Remote 3.x interface =com.sample.TestEjb,ejb-link=null,lookup=,mappedName=,jndi-name=com.sample.TestEjb,refType=Session into class com.sample.StartupEjb: Lookup failed for 'java:comp/env/com.sample.StartupEjb/testEjb' in SerialContext[myEnv={java.naming.factory.initial=com.sun.enterprise.naming.impl.SerialInitContextFactory, java.naming.factory.state=com.sun.corba.ee.impl.presentation.rmi.JNDIStateFactoryImpl, java.naming.factory.url.pkgs=com.sun.enterprise.naming}
网络逻辑:
Caused By: weblogic.application.naming.ReferenceResolutionException: [J2EE:160200]Error resolving ejb-ref "com.sample.StartupEjb/testEjb" from module "sample-web-1.0-SNAPSHOT.war" of application "com.sample_sample-ear_ear_1.0-SNAPSHOT". The ejb-ref does not have an ejb-link and the JNDI name of the target bean has not been specified. Attempts to automatically link the ejb-ref to its target bean failed because no EJBs in the application were found to implement the "com.sample.TestEjb" interface. Link or map this ejb-ref to its target EJB and ensure the interfaces declared in the ejb-ref are correct.
Glassfish 和 Weblogic 都找不到 TestEjb!
顺便说一句,当我为 TestEjb 创建一个远程接口并将其用于注入时,它运行良好!但我不想定义远程接口,我想使用没有接口的 EJB。我不认为我必须为这个简单的用例定义一个远程接口!
